To all vwhom 'it may concern.'

Be it known that I, JOHN E. GILsoN, a citizen of the United States, andresident of Port IVashington, in the county of Ozaukee and State ofWisconsin, have invented certain new and useful Improvements in Port--able Frames for Transmission-Gearing; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

The primary object of my invention is to provide simple, economical andeffective transmission gearing and frame therefor, the construction andarrangement being such that interchangeable counter-shafts are providedand arranged to be adjustably mounted upon longitudinal struts, whichstruts are secured at their opposite ends to the engine body comprisingone of the frame members, the struts being preferably in the form ofU-shaped loops. The counter-shafts are provided with transmission gearwhereby power is applied to machine elements in juxtaposition to theframe.

lVith the above objects in view my invention consists in variousstructural features and combination of mechanical elements ashereinafter described with reference to the accompanying illustrationsand subsequently claimed.

In the drawings Figure 1 represents a plan view of an internalcombustion engine provided with a gear transmission attachment embodyingthe features of my invention; Fig. 2, a side elevation of the same withparts broken away and parts in section to more clearly illustratecertain structural features, and Fig. 3, a detail plan view.illustrating a counter-shaft equipped with a transmission gear in theform of a series of pulleys, which counter-shaft may be substituted forthe counter-shaft and its transmission gear as illustrated in Fig. 1 ofthe drawings.

Referring by characters to the drawings 1 represents an engine baseprovided with feet 2, to which engine base is secured the cylin der 3,the walls of which extend upwardly to form an open water cooling tank aas shown, the entire structure constituting a master casting that formsthe basic part of a portable frame for transmission gearing.

Mounted upon the base 1 is the usual crank-shaft 5 that is connected tothe piston 6 by a pitman 7, the crank-shaft being also provided withstandard fly-wheels 8, and a drive-wheel 9, which, in this instance, isshown in the form of a pulley. The engine is also provided with theusual` valve mechanism 10 that is operated by a cam-carrying gearewheel11 through a pinion 12 carried by the crank-shaft, all of whichconstruction forms no part of my present invention. The cylinder 3 isprovided with apertured ears 13 that extend laterally in eitherdirection from the side-walls thereof. The ends of upper stretches 111of longitudinal struts are secured to these ears 13, which strutscomprise open end loops having vertically disposed stretches 15 andbottom stretches 16 that extend under the feet of the engine base andare secured thereto by bolts 17, the vertical stretches of the strutsbeing disposed rearwardly yof the engine cylinder or in the oppositedirection to which power is applied to the crank-shaft. The struts areeach preferably bent up from a single piece of U-shaped angle-iron,their bottom stretches being supported upon front and rear truck-members18, 18, it being understood, however, in some instances` said truckmembers may be supplemented by suitable skids.

. The vertical stretch 15 of each strut is provided with a series ofapertures 19 for the reception of retaining bolts 2O of a supportingmember 21 of a two part box, the cap member 22 of the box being hingedto the supporting member 21, which latter has a slotted iiange 23 forengagement with one set of the retaining bolts 9.0, whereby said capmember is secured. A counter-shaft 2a is journaled in the boxes, whichcountershaft carries a pulley 9 that is in belt gear connection with thecrank-shaft pulley 9. A hanger 25 is provided with boxes at one endthereof, whereby said hanger is suspended about the counter-shaft. 24.The opposite end of the hanger carries a single box 27, into which isjournaled an arbor 28 having a gear-wheel 29 secured to one end and adisk 30 at the opposite end thereof. The arbor is also journaled inbearings 31 of a bifurcated clip 32, which clip bearings abut theopposite ends of the hanger-box 27, whereby a hinge connection is formedabout said arbor relative to the clip and hanger.

The clip has an apertured flange for the reception ot retaining bolts33, that engage a separable saddle member b4 of said clip, whereby thesame may be readily attached to a pump column 35, as shown in Figs. 1and 2, or other machine element. Both the gear-wheel 29 and disk 30carry crank-pins 29 and 30a respectively to which cranlcpins areconnected pitmen 3G, 36a, the pitmen being provided for connection withthe pump piston rod 37 by any suitable means, not shown,

The counter-shaft carries a toothed pinion 38, by means of which drivetherefrom is imparted to the gear-wheel 29, through an idle pinion 39that is interposed between the lirst named pinion and gear-wheel, theidle pinion 39 being journaled upon a stud 40 that is carried by thehanger 25. The clip, gearewheel 29, and disk 30, with their variousconnections carried by the bracket, thus constitute a pump-jack, whichas stated, constitutes means whereby the engine can be readily coupledto the pump or other mechanical element to which power is to be applied.The hanger being in hinge connection .f'ith the counter-shaft and arbor,permits imple scope for adjustment with relation to elevation of thegear connection between said engine and pump. It will also be observedthat the journal boxes oi the counter-shaft may be adjusted to variouselevations and secured by the retaining bolts 20 that are. fitted intoany one of the separate sets of the strut apertures. Vhen it is desiredto supplement the counter-shaft driving-gear illustrated in Figs. 1 and2 oi' the drawings with a counter-shaft equipped with a stepped pulley41, as shown in Fig, 3, the same may be readily accomplished byloosening one set of the retaining bolts 2O whereby thev hinged capsections 22 of the boxes may be' swung backward for the removal ofcounter-shaft 9.4, the counter-shaft 24a carrying the pulleys 41 beingthen dropped into position within the boxes.

It is desirable to provide means for tightening the belt through whichmotion is iniparted to the counter-shaft pulley 9a Jfrom i thecrank-shaft pulley 9 and with this in view one end of an invertedL-shaped brace beam 15 is secured to a strip 16 oi one of the struts.The brace beam 15 is also secured to the upper stretch 14 of this strut,a leg 15 being extended across the frame and is secured at its end tothe upper stretch 14 of the opposite strut thus forming a brace for thegear-carrying frame comprising the parallel struts previously described.The vertical stretch of the brace beam 15 is slotted tor the receptionof a stud 9b that is adj ustably secured thereto by means of a retainingnut in threaded engagement with said stud and mounted upon the stud is abelt tightening roller 9c adapted to operate upon one stretch ot thedriving belt between puileys 9 ant 9CL whereby said belt is adjusted asto slack. The counter-shaft 24a,

shown, is also equipped with a clutchpulley 42, whereby power may beapplied to a separator or any machine or element wherein it ispreferable to employ a clutchpulley transmission.

The idle ninion 39 through which )ower is transmitted from thecounter-shaft to the gear-wheel 29 is inserted for the purpose ofovercoming the reverse drive of said gearwheel which would occur, shouldthe same be directly meshed with the counter-shaft pinion 38, but itshould be understood that, in some instances, reverse drive upon saidgearwheel may be desirable, in which case the idle pinion would bedispensed with. It is also obvious that any suitable form of gearing maybe employed to transmit power from the engine crank-shaft to thecountershaft and from thence to the machine element other than thatshown and described.

The front truck 18 is provided with a iifth-wheel while the rear member1S is rigidly secured to the struts. The front truck member comprises atubular aXle 43 which is fitted with a centrally disposed saddle 44, thesame being secured thereto by a U-shaped clip-bolt 45 having threadedends that engage ears of the saddle 44, the bolt being clamped theretoby suitable nuts in threaded engagement therewith.

The saddle 44 is provided with a circular face-plate having a centrallydisposed shouldered aperture for the reception of a headed king-bolt 4T,which king-bolt passes through an apertured fifth-wheel disk 4S, thedisk being provided with a rectangular hollow block extension 49 that isseated within a transversely disposed U-shaped girder 50. This girder issecured to the bottom stretches 16 of the struts by the bolts 17, which,as previously mentioned, also anchor the engine-base to said struts.

The rear truck-member comprises a hollow axle 43a, which axle is securedto the bottom struts 1G by bolts 5G that pass through apertures in theaXle and alined apertures in said struts, there being hollow spacingchairs 5T interposed between the struts and axles. .Each chair isprovided with longitudinal flanges that engage the side faces of thestruts whereby a rigid joint is formed therebetween, the lower walls ofthe chairs being also provided with curved seats into which the axle isseated. The rear axle is provided with truck-wheels 54a that are heldagainst lateral play.

While I have shown and described a speciiic forni oi" truck upon whichthe engine is mounted for transportation, it is underderstood that l donot wish to claim the same or be confined to the structure of saidtruck, it being within the scope of my invention to mount the engineupon skids in some instances as a substitute for the truckwheels.
